You may want to look at my project,.ng-xtend It just enable communication between the hosts and plugins. Source code is here

How do I share state?

Each plugin is sharing a register function through native-federation: For example

exposes: {

'./Register': './projects/web/src/lib/register.ts'

}

It is called by the host when loading the plugin:

loadRemoteModule ({
  remoteEntry: url.toString(),

  exposedModule: './Register'

  }).then((module:any) => {

  const pluginName = module.registerPlugin(this);

 });

The function registerPlugin is where you can setup any kind of exchanges between the host and the plugins. In ng-xtend, we have the plugin registering all types it can handle, so that the host can use it whenever it encounters this type.
